To all lwhom it may concern Be it knownthat I, GEORGE Ansir, a citizenof the, United States, residing at Paterson, in the county of Passaicand State of New Jersey, have invented certain new and usefulImprovements in `Warping Machines, of which the following is a Thisinvention relates to warping machilies of the class in'which thecarriage for the reeds and warp guiding-rolls is travel-sable crosswiseand arranged atl one endzof the frame. The invention has for itsprincipalobjects to mount the carriage so that it may be moved withconsiderably greater freedom than heretofore, both when traversedautomatically and when reset manually; to simplify the construction ofand the manipulations necessary to operate the disconnective connectionbetween the carriage and its rotary feed-screw or worin; and to providean improved form of gage for determining the resetting positions of thecarriage when the machine is used for section-warping.

In the drawings, Figure l1 is a side elevation ofthe reedcarria e endrof a war ind machine con structed according to the invention;

Figure 2 is a plan ofv what is shown in Fig. 1;

Figures 3 and 4 aresectional views on:

the lines 4 4 and 3-'-3 of Figs. 4 and y3, respectively;

Figure 5 shows a detail; and 4 Figure 6 is View illustrating`principally the gage, which appears yin side elevation. v

a is the frame of the machine having. suitably fixed in arms bprojecting therefrom the horizontal transverse round rod or shaft c, andalso having below this shaft a horizontal'tra-nsverse brace-rail orstrut d which is in the present'case a channelrail with itsopen sideoutward and forms a part of the frame proper.

The carriage for the reeds and warp guiding rolls is constructed asfollows: c is the hollow box-like body-portion of a casting whichincludes spaced arms 7 ,projecting forward fromsaid body-portion. at thesides thereof and bored at g in alinement-with each other to receive thelshaft c, each armbeing further, provided with a rearward and upwardlyinclined slot 7L eX- tending from said bore. In the slot of each arm isjournaled a vroller having a peripheral groovev of a cross-sectiontojsub'- stantially conform withk that of shaft c.

To ythe front faces ofth'efaims,`which are planed offsmooth to the samevertical plane, 1s secured ,a vertical plate or apron j, to

which further reference will be made. Upon? bolted to the under side ofthe bOdLPOltion e of the. carriage.A avertical ystud a secured in andprojecting from the lower end of this leg is journaled a roller oadapted to bear. on the guideway whichis formed by the edge of one oftheliangesthere the upper one) of therail or strut d. Connectingthe stud`and the free end portion-of the struc! ture Z is a brace p, beingsuitably secured rigidly to both 'of'thenLr The carriage, receiving' thelguide-rod iii its bores g, is supported principally' by the Contact ofroller v1 upon theY guide`-rod,which forms a main guideway extendingtransf versely ofthe machine and facing upwardly andv alsolrearwardly,so that nearly allnof the force of gravity acting onthe carriage (to4wit, both directly downward and indirectly as the result ofthe 'centerof gravityl of the carriage being Outward of the guide'- y rod and thecarriage having a purchase or fulcrum at d o) is opposed byv saidlguiderod. In consequence of this constructionl and arrangement thecarriage is movable with the greatest freedom along the gui'deway.

In ordinaryfwarping machines the carriage' is usually arranged to travelon two guiderods arranged in a horizontal rplane'or otherwise so`thatthe force of gravity act-` ing-'on the carriage is opposed by bothguide-rods substantially equally, which sets up, a binding sovconsiderable that even if anti-friction means is employed itrequiresconsiderable exerti `ml on the part ofthe attendant to move thecarriage by; hand when resetting and Y fortransniitting theA powernecessary for traversing the carriage automatically the transmissiongearing has to be designed with special regard to the resistance thuspresented.

To take up any lost-motion which might exist in the bores g between theguide-rod and carriage and which might manifest itself if the warperpushed baclrwardly on the carriage with suilicient force as he manuallyshifted it along the guide-rod c I provide rollers g which are journaledin the forked inner ends of cylindrical blocks r that are arranged inbores S ext-ending from the front faces of the arms f inward to therespective bores g, said blocks being adapted to be adjusted to bringthe rollers g against the guide-rod by setescrews 15 tapped into lateralears u projecting from the apron The Aapron has a hub j in which isjournaled the hollow spindle i; of a worm-wheel w in mesh with the worinm suitably journaled in the frame of the machine adapted to be driven inwarping from the reel or other going part thereof by any well knownmeans (not shown;) to keep the worm against springing` away from theworm-wheel an inwardly projecting portion of the apron has suitablysecured therein a saddle piece l1/ formed with a grooved seat for theworm. The spindle of the wormwheel has a suitable handle z fixed thereonwhereby to turn the worm-wheel and so feed the carriage. as inresetting, manually. There is a novel screw-and-nut device for clampingthe worm-wheel against turning in the carriage, so that the rotatingworm will cause automatic traverse of the carriage. The inner face ofthe worm wheel has a conical recess fw in which is set a conical nut 2which is kept from turning and'also retained in place by an arm 3 whichis secured to the carriage and has its free end engaged between lugs 2on the nut. The screw of said device consists of a threaded spindle 4having a threaded engagement at one end with the nut and a h andie Livat the other. When the screw is turned in one direction said deviceobviously binds the worm-wheel in the carriage against turning, and whenthe screw is turned in the other direction the wormwheel is left free torotate.

In one of the ears u is arranged a longitudinally and horizontallyslidable rod 5, which may be secured at any position to which it ismoved by a set screw 6. On the guide-rod c a collar 7 is adapted to besecured at different stages by a set-screw 8. This collar has aforwardly projecting pair of arms 9 10, the arm 10 havinga lug l0 whichis adapted to overhang thev rod 5. in the' two arinsv 9 l0 is 'pivotedon a transverse horizontal axis an abutment device 1l .having a thumb'piece 12 that' is `adapted to and contact with a shoulder on the collarformed at 13 and thereby form a stop to the upward pivotal movement ofthe abutment device. In section warping the rod is Xed in the carriageso as to project therefrom a distance corresponding to the width of thesections to be warped. The carriage being then placed at the point forstarting the winding on of the first section, the collar 7 is shifted onguide-rod c until, the attendant having elevated the abutment device 1l.the latter contacts with the end of the rod 5, whereupon the collar issecured in its new position.l The warping ofthe first section is nowproceeded with. and when it is completed the warper returns thecarriage, which has meanwhile been tra- -versed automatically to theright, until the side of f contacts with the near end of the collar 7,abutment device ll havingbeen allowed to fall to the position shown inthe drawings; the return movement of the carriage is equal to thetraverse length plus the width of the section, the latter beingdetermined by the extent to which rod 5 is adjusted to project to theleft. Then the collar 7 is released and.l being kept from' falling bythe lug l0 resting on rod 5, it is moved to the left until the abutmentdevice can be again elevated and made to hear against the end of the rod5, whereupon it is secured to the guide-rod in readiness for gaging thenext resetting movement of the carriage. So far as I am aware, it isbroadly new to provide a gagingmem'- ber, as 5, adjustable laterally ofand inthe carriage to different positions, a carrier member, as Lsettable laterally of the -carriage and in the frame vto different posi#tions and adapted to be abutted by the carriage, and a detent device, asl1, movable in the carrier member into and out ofthe path of the gagingmember and when in said path adapted to be abutted thereby.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is :wl
